100
This type of intermolecular forces is present in all atomic and molecular interactions.
What is London Dispersion Forces?
100
The picture below represents oxygen molecules. This would be the shift to the curve if this represented hydrogen molecules.
What is to the right?
100
This technique involves separating a colored solution based on its polarity.
What is chromatography?
100
These solids do not conduct electricity in their solid form but they will when dissolved in water.
What are ionic solids?
100
This is emitted from an atom when energy is released.
What is a photon/light?
200
This term describes the ability of an atom or a molecule to form temporary dipoles due to the movement of electrons in weak intermolecular forces.
What is polarizable?
200
These behave as if there are no intermolecular forces present. When the molecules collide, the collisions are elastic.
What is an ideal gas?
200
This calculation does not appear on the AP Chemistry formula sheet but is worth memorizing and is useful when making dilutions.
What is McVc = MdVd?
200
Examples are Quartz and Diamonds
What is covalent network solids?
200
The color of light produced by a photon with a frequency of 6.7 x 1014 Hz.
What is violet? (I will also accept BLUE!)
300
This type of intermolecular force occurs when a hydrogen atom bonding to a highly electronegative atom such as hydrogen, oxygen, or nitrogen is attracted to a lone pair of electrons on a nearby electronegative atom of a different molecule.
What is Hydrogen Bonding?
300
The partial pressure of Argon when a sealed vessel contains 0.200 moles of oxygen, 0.100 moles of nitrogen, and 0.200 moles of argon; the total pressure of the gas mixture is 5.00 atm.
What is 2.00 atm?
300
The mass of NaNO3 required to make 100.0mL of 0.45 M solution.
What is 3.8 grams?
300
These solids have relatively low melting points and they do not conduct electricity.
What are molecular solids?
300
The energy of a photon of red light with a wavelength of 670 nm.
What is 2.97 x 10-19 J?
400
The effect on boiling point when the strength of the intermolecular forces increases.
What is boiling point increases?
400
The moles of a gas that occupies 2.5 liters at 1.2 atm and 25 degrees Celsius.
What is 0.12 moles?
400
The amount of water needed to dilute a 0.100 M stock solution of Cobalt (II) Chloride to produce 25.0 mL of a 0.050 M solution.
What is 12.5 mL?
400
These are broken when a molecular solid melts or boils.
What are intermolecular forces? (NOT the covalent bonds!)
400
The concentration of an unknown solution with an absorbance of 0.898 where the standard curve for Beer's Law is y = 6.3x + 0.135.
What is 0.121 M?
500
The effect on vapor pressure of a liquid as intermolecular forces decrease?
What is vapor pressure increases?
500
The volume of the balloon if it is initially at sea level (1.00 atm) with a volume of 2.30 Liters at 23.5 degrees Celsius and the rises to a new height of 25,000 feet with a pressure of 0.810 atm and a temperature of 12.0 degrees Celsius.
What is 2.73 L?
500
The processes that salt (NaCl) and vinegar, otherwise known as acetic acid (HC2H3O2) do when they dissolve in water.
What is dissociate (NaCl) and ionize (HC2H3O2)?
500
These are considered good conductors of electricity as their electrons are free to move.
What are metallic solids?
500
The effect on the concentration of an unknown solution if the outside of the cuvette is not cleaned during a spectrophotometric analysis.
What is increase?
